Tax Over-Collection and Common Mistakes

Possible causes of tax over-collection and how to fix them:

Mismatched Tax Categories Between Galvix and Your Billing System

If the tax category assigned to a product in Galvix does not match the one in your billing system, it can lead to over-collection.

Open the Transaction Details page and review the Tax Category and Tax Rate applied to the affected line item.
Compare these values with the corresponding tax category and rate in your billing system.
If there’s a mismatch, update the tax category in either Galvix or your billing system to ensure consistency.

If a customer is tax-exempt, but the tax was collected, it can result in over-collection.

Verify if the customer has an exemption record in Galvix.
If the exemption exists in Galvix, check if the same exemption is applied in your billing system.
If the exemption is missing in the billing system, add it there to match the exemption data in Galvix.
Go to Settings → Integrations in Galvix, click the 3-dot menu next to your integration, and select Resync to update the latest changes from your billing system to Galvix.
Recheck the tax difference after syncing.

If the issue persists, proceed to the next step.

If a transaction was mistakenly flagged as exempt in Galvix but not in your billing system, it could lead to over-collection.

Check if an exemption was applied to the customer in Galvix.
Cross-check whether the billing system also has the same exemption.

- Navigate to Settings → Integrations, click the 3-dot menu next to the integration, and select Disable.
Recheck the transaction to confirm the correction.

If the issue persists, proceed to the next step.
